Sample Period

The sample period determines the time between samples. Enter the time you wish to elapse between each Temprecord sample.

With the Mk3 and Mon-T loggers you can set the sample period in multiples of 2 seconds. You can enter any value between 2 seconds and the upper limit of 24 hours. These loggers have an internal time resolution of 2 seconds. This means that whatever value you enter must be a multiple of 2 seconds. The time is specified in hours, minutes, and seconds.

With the LCD logger you can set the sample period in multiples of 1 second. You can enter any value between 1 second and an upper limit of 18 hours and 12 minutes and 15 seconds.

If you enter a sample period greater than these values, it will be limited to these values within the logger. The screen also calculates the logging duration, being the time to fill the logger based on the current sample rate.

When you have entered all the data you wish to alter, click on 'OK' to update the parameters and exit the form.

Click on 'Apply' instead if you want to update the data in the logger, but not exit the form. This can be useful where you have several loggers to set up, each with the same or similar parameters.

Once the logger has been started, you cannot alter the user data, password, sample period or start delay. Check that these are correct before you start the logger.

The sample period also affects the behaviour of the limit delay and Safe range. These parameters both use units of the number of samples taken, so the time delay before they act is dependent on the sample period.

When a logger is reused, the sample period that was in effect for the previous use is retained. If you require a different sample period, this should be programmed after the logger has been reused.

If the logger is a humidity logger, and both humidity and temperature are enabled, the sample period applies to both, i.e. if you set a sample period of one minute, a temperature and humidity sample pair will be taken every minute. In this case the number of samples taken before the logger is full (the logging duration) will be halved.
